Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system, 3-Chloro-4-fluoro-3-(4-fluorophenyl)-propiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
3-Chloro-4-fluoro-3-(4-fluorophenyl)-propiophenone (CAS 898768-49-5), molecular formula C15H11ClF2O and molecular weight 280.70 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Chloro-4-fluoro-3-(4-fluorophenyl)-propiophenone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
